Referring to the drawings, one embodi-l ment of thisv inventioncomprises a talking'.

machine i/ncludingthe usual or any suitable cabinet providing'a flathorizontal partition or support 10,`spaced above which is a horif Zontalrotary disk record support 11, adapted tocarry the usual orany suitabledisk sound record l2, the record shown being provided on its uppersurface with a spiral sound groove 13 of uniform depth and in v the formof lateral undulations correspondingto sound waves. The record support11 Vis provided With a .marginal -cylindrical flange or rim 14dependingtherefrom and integral or otherwise rigid therewith, for apur-.pose that will appear hereinafter. The record support is carried bythe upper end of a rotary spindle 15, which projects upwardly freelythrough an aperture 16 provided therefor in the support 10. The spindle15 is mounted to rotate about a fixed vertical axis coincident with itslongitudinal axis in suitable bearings depending from a rigid motorsupport 17 arranged beneath and secured to the horizontal support 10.

For rotating the record support 11, an electric motor 20 is arrangedbeneath the horizontal support 10 and is rigidly secured to the motorsupport 17 in any suitable manminally connected by any suitable couplingmovement in any suitable manner.

mounted upon or integral with the spindle I 22 with a horizontal drivingspindle 23 in alinement therewith, and which is mounted to rotate abouta fixed horizontal axis `in suitable hearings 24, and 25, depending fromand rigid with the motor frame 17, the

spindle 23 being held against longitudinal Rigidly v28 and coaxialtherewith is a worm 26 which engages a worin gear 27 rigid and coaxialwith thevertical spindle 15, whereby the spindle 15' is rotated torotate the record support.

Mounted upon the horizntal spindle 23 is a governor including balls 28carried by springs 29, securedvto a collar 30 fixed on the drivingspindle4 23, and to a sleeve 31 slidable longitudinally of the drivingspindle 23, and carrying fixed thereon a frictionl` disk 32 whichengages va friction pad 33 carried by` anvarm 34 rigid with a shaft 35,which is rotatively adjustable by well known means (not shown) to causethe motor and record support to rotate at a predetermined rate. L

Above the record 12 is the usual or any suitable sound box or soundreproducer 40,

therewith, and to swing across the record 12, the tone arm beingsupported at its larger end by well known means (not shown) to swingabout a' fixed vertical axis.- The sound box 40 is provided with theusual or any suitable stylus 42 arranged to coperate with the soundrecord 12v by engagement'in the undulatory sound groove 13 forpropelling thel sound box'A across the record to re'- produce thesounds' recorded upon the. record.A

Forl starting or stoppingl the 'rotation of the record support 11, andthe record 12 carried thereby, automatic means are provided which arepreferably arranged mainly 'upon the upper surface of the horizontalpartition or support` 10 and beneath the rotaryvrecord support 11 andcomprising .a substantially flat horizontal base plate 45 which isrigidly secured by means of screws- 46 lor otherwise'to the uppersurfacejof the horizontal supportlO, the major portion of l the baseplate being beneath the record sup'- vport 12, but one edge of the baseplate rojecting slightly laterally" outwardly rom the margin of therecord support as at 47 in order to display the words on and ,oif prother suitable lettering which may be impressed Ainto the upper surfaceof lthis A L projecting portion of the base plateV for a purpose whichwill appear hereinafter.`Vv

Arranged slightly above the base plate is a switch and brake lever48which is mounted to oscillate about a fixed /vertical pivot 49extending snugly through an aperture provided therefor in the baseplate, a washer 50 being preferably interposed around the pivot 49between and in contact with the under surface of the switchlever 48 andthe upper surface of the baseiplate 45, and the pivot 49beingpreferably'provided above the switch lever with a head 51 having afiat under surface which engages against the upper .surface of theswitch lever to hold the switch lever rotatably Ain position. The switchlever 48 extends from the pivot 49 outwardly beneath the marginal flange14 of the record support, and terminates in an upwardly oi-set portionextending outwardly from the pivot 57, the lower end of which is rigidlyv secured to the base plate 45, and the upper endof which is providedwith a head 58,

vthe lunder surface .of which engages against thevupper end of thesleeve 56 to prevent which is connected to the smaller end .of a.;hollow tapering rtone arm 41 to communicateupward movement of thesleeve. The free end of the `latch 5,5 isA provided with a laterallyprojecting outwardly tapering tooth .59 arranged .to engage in acorrespondingly tapered notch 60 provided therefor in the edge of theswitch lever 48 adjalcause the rotation of the record support, as

will appear hereinafter. y

For performing the double function of holding the tooth 59 of the latch55 in engagementwith the notch 60 of the switch lever 48, and ofswinging the switch'lever 48 anti-clockwise from an operative or on toan inoperativeA or oil position, when the latch 55 is released fromengagement with the switch lever 48, a spiral spring 65 or otherresilient means is secured atv one end to alug 66 projecting upwardlyfrom the `latch' 55, while the other end of the said spring is attachedto a lug 67 which -is preferably integral with the switch lever 48.These lugs 66 and 67 are 'so positioned that when the tooth 59 isinengagement with its notch 60, as shown in Fig. 1, the longitudinalaxis or line of action of the spiral spring 65 is spaced slightly infront of the tooth V59, and between the tooth 59 and the longitudinalaxis of the vertical pivot 49, and -between the tooth 59 and the axisofoscillation of the latch 55, and ;,axtends ,ina direction nearlyradial with respect to the axis of oscillation of the latch 55 1n thisposition the spring acts to hold the `tooth 59 in enoagement in itsnotch 60, but by swinging the latch 55 through'a small areanti-'clockwise, the spring will act` edectively to rotate the switch`lever 48 anti-clockwise into an inoperative or off position, as shown inFigs. 2, 3 and 5.` In the latter position the spring 65 acts to hold therear edge of the free end of the latch 55 lightly in engagement with afixed stop 68 provided theren i for and projectingupwardly from the baseplate 45, and maintains the tooth 59 1n such a position that lonly aslightrotary move,- rnent clockwise is necessary to bring it intooperative engagement in its notch 60 after the switchlever has beenrotated manually to bring the notchinto alinement with the tooth.

When the tooth 59 is in engagementinits notch 60, it may be released orthrown out of engagement at any time by a slight pressure vanti-clockwise exerted manually or otherwise upon the switch lever 48,in addition to the pull of the spring 65,1theyf-outer side edge of thetooth and the corresponding wall of` the notch being inclined `in asuitable direction to produce this eect, and when the tooth 59 is out ofengagement with its notch and in its normal inoperative position, asshownin Figs, `2, 3 and 5, itfmay be broughtinto engagement in the notchsimply by manually rotating the switch lever 48 clockwise. The "innerSide edge of the tooth to the switch Yleyer 48,.

59 and the corresponding wall of the notch 6 0 are preferably so shapedas to maintain the tooth in engagement in the notch against any pressurethat may be applied clockwise For automatically releasing the latchfrom"engagement with the switch lever 48 a horizontally extending arm 70is mounted "at one end to rotate about a vertical axis upon the sleeve56, and projects from the sleeverearwardly and terminates in the rear ofthe margin of the record support 11 in a bifurcated end forming twofingers 7"'1 and 72. The inner end of `one,71, of these fingers isarranged to be engaged and actuated by the lower end of a verticalstud-73,.

which is rigidly secured. at its upper `end to` the under side ofthetapering tone arm 55 41. The other finger 72 of the "arm 70 ispreferably provided at its outer end with an upwardly extending stud 74in the form of a handle for the convenient manual operation oradjustment ofthe arm 70.`

To transmitmotion from the arm 70 to the latchfi, and at the same timeto permit 'upper surface of the base plate 45.

stud 73 at Vany desired position, the arm 70 and the latch 55 arepreferably yieldingly clamped in a predetermined` relationshlp by meansof a 'yielding spl1t washer or U-shapedfspring clip 75, made of springsteel, or other suitable material. The spring clip 75, when in operativeposition, partially surrounds the sleeve 56,'coaXial-therew1th,

and engages against and istheld in position by the walls of an annulargroove 76, providedtherefor in the sleeve 56. This clip 75 isl normallyin contact with and. presses downwardly against the upper surface of thecorresponding end of thelatch 55, which is preferably arranged above thecorresponding end of the arm 70. A washer 77 of beror other suitablematerial is preferably laced around the sleeve 56, between the a jacentends of the latch 55 and the arm 70, and a similar washer 78 isinterposed around the sleeve 56 and between the under surface of thecorresponding end of the arm 70, and an annular flange 79 which projectsoutwardly from the lower end of the sleeve 56, .preferably integraltherewith and the tatedmanually with respect to the sleeve 56,

andthe latch 55, by exerting a force on the handle 74 slightly in excessof the force exerted by the tone arm in coperating with the nger 71 todisengage the tooth 59 from its notch 60. y

For automatically controlling the electric motor 20 there is arrangedbeneath and depending from the base plate 45 and coaxial with the pivot49, an electric switch comprising a vflat circular horizontal base 85,of fiber or other insulating material, the upper surface of which isprovided centrally with a 'circular recess 86, in which snugly fits thelower end of the vertical pivot 49 of the switch lever 48. The base 85is surrounded by a suitable vertical cylindrical switch casing 87,whichf may be provided with a suitablewlining S'fof insulating Ina,-terial, and which fits snugly in a cylindrical aperture providedtherefor in the horizontal partition 10. The lower end of the casing i87 `fits snugly ingan annulark marginal recess provided therefor in theupper surface of the circular base, and the base 85 and casing 87 areclamped in xed relationship by means of vertical screws 89 extending 'vers 105 of insulating material surrounding through i the base andthreaded into' the base plate 45.

Within the casing 87 and mounted upon and projecting through thecircular base 85, are a pair of stationary brass binding or terminalposts 90 and 91, the upper ends of which are provided with datrectangularheads 92 and 93, which are held against rotation inrectangular recesses provided therefor in theupper surface of thecircullar base 85, and clamped downwardly upon I' the lower portions oftwo 'brass plates 94 and 95, which are bent upwardly from the heads andthen inwardly to form two diametrically opposed stationary horizontalcontacts 9G and 97. Stationary brass bushings 98 and 99 may be arrangedin recesses provided therefor in the under side of the circular base 85and surrounding the binding posts 90 and 91 respectively. Surroundingthe ixed vertical pivot 49 and within the casing 87 is a rotatableswitch member comprising four superimposed plates 100, 101, 102 and 103,each of which is held in fixed relationship with respect to each otherby means of two vertical rivets 104, the bottom plate 100 and the topplate 103 fitting snugly but rotatably on the vertical pivot 49 andbeing spaced and insulated from the intermediate plates 101 and 102 bymea-ns of `washthe rivets 104. The intermediate plates 101 and l102 areclamped together" between the washers 105 and provided with suitable.

against movement longitudinally of the" pivot 49 by means of suitablewashers 108 and 109 preferably of insulating material, surrounding thepivot 49 between the top plate 103 and the under surface of the baseplate 45, and between the bottom kplate 100 v and the upper surface ofthe circular base 85 respectively. For rotating the movable contacts106- and 107 of the switch, the top plate 103 is provided with avertical extension 110, which projects loosely through a segmental slot111 in the base plate 45 coaxial with the lvertical pivot 49 and engagesin an aperture 112 provided therefor in an extension of the switch lever48. A iexible electric conductor 115 extends from the binding post 90 tothe motor, for supplying the motor with an electric current, andaiexible electric conductor 116 extends from the binding post 91 to asource of electric current. Ay flexible electric return conductor 117from the motor to the source of electric current completes the motorcircuit when the movable contacts 106 and 107 of the I' switch are inengagement with thefstationary contacts 96 and 97.

For stopping the rotation of the record support 11 substantially' at thesame time that the switch lever 48 is rotated anti-clockwise eitherautomatically or manually to break the circuit of the motor 20, theswitch, l

55 out of engagement with its notch 60, the

brake pad 122 being pressed against the marginal flange 14 when in thisposition by the action of the spring 65, and the brake pad 122 holdingthe switchA lever 48 just out of engagement with the free end of thelatch 55. g

To prevent the motor from being unintentionally operated through anindefinite period, auxiliary automatic mechanism isprovided, whichoperates independently of the position of the sound box 'with respect tothe record, to release the tooth 59.01? the latch 55 from its notch 60to break the motor circuit and` to apply the brake after vthe motor hasbeen in operation continuously at any time for a period slightly greaterthan would be required to reproduce the sounds from the largest recordfor which the talking machine is designed.

One embodiment of the secondary automatic mechanism comprises a worm 125coaxial with and rigidly secured to the vertical end of the spindle 15,whichcarries the record support. This worm 125 is preferably arrangedbeneath and in` engagement with the rigid motor support 17, and en-rgages a corresponding worm gear 126 which is coaxial with and rigidlymounted upon" a horizontal rotary shaft 127, adjacent one end thereof.This shaft 127 is terminally supported in suitable stationary bearings128 and 129, which depend from and are rigidly secured to the motorsupport 17, the shaft 127 being heldagainst longitudinal movement tinany suitable manner. The end of the shaft 127 opposite the wormgear'1265is provided with a worm 130 coaxial and rigid therewith whichengages a horizontal worm gear 131, which is loosely mounted upon thelower portion and adjacent the lower end of a vertical rol @www taryspindle132, which projects upwardly Y Itherefrom and snuglyvbutrotatablythrough a cylindrical aperture "therefor UPP slightly belowtheun er surface` of the base y' o or bearing provided in'.7 the `motorsupport 17. y The r end lof the s indie 1132 is spaced late 45 andeixtends4 intol a vertical` clin dr oriu calfaperture 133 provided inthe zontal'partition 10. jThe spindle 132 is held ilat "annular Bange134"integ)ral 0r otherwise rigid therewith' which ....131 lfrictionally,against.` rotation with re- `spect; to its; rotary .spindle 135` whilethe against upward `movem`ent by means `oi a against the under surfaceof the motorsup a port 17, `and" is held ,againstu downward movement by.means of` a collar 135, which surrounds the spindle and bears againstthe npperfsurfaceofgtho support 17, and which is rigidly but detachablysecured-fte the spindle by means of a horizontal `pin 136 extendingdiametricallylthrough Ithe `collar `and, the spindle. y y,

. which engages against the upper side of the bell crank 15'5. Awasher158 is preferably interposed around thepivot i156 between'the tween thecrank Vplate 4151 and theiront edge 'of thclatch 55. Thisbellcranl 155is` `:nrsmgedr to oscillate about a; fixed vertical ico.

bell crank 155 and theuibase. plate 45,120 holdy the bell crankshghtlyabove the upper sur,

face of the base plate and in a plane with the crank plate 151. Theinner end 159 of the bell crank 155 is arranged to 'normallyenl gagethelfront edge of the latch 55 as at 160,A r

and the frontend 161 of the bell crank is arranged to be always intthepath ofthe beveled-edge 154 fof the lug.y 154 of the "crank plate 151.'`The bell crank 155 haslonly a small amount of free `rotary movement, the

rotation of the bell crank in a clockwise dil rection being` limited vbya' fixed stop 162,' which projects upwardly fromthe rbase plate 45 andpreferably integral therewith,-

and which is arranged to engage aside edge of the frontrportion of thekbell crank 155,

and the. rotation ofthe bell crank anti-l clockwise being limited byythe-frontedge of o the latch 55, when the rear ed'geof the latch is inengagement; with its stop l68.

To resetthe crankv plate 151' after `it has .performed leasing theswitch lever 48, as'just described, a pushbar 165is mounted toyoscillate about a vertical its function of automatically re-V pivot 166extending through one l end of 1.the pushgbar andrigidly secured at itsi Y from the switch lever lower end to an arm 167 projecting forwardly166 being provided with' a head 168 bearing against the upper surface ofthe push bar 165 to hold the push bar slidably in engagement with theupper-surface of the arm 167. l

The inner portion of the push bar is fiat and horizontal and theoutei'portion of the push bar is also iiat andl horizontal but is offsetslightlyupwardly from the inner portion so that the under surface of theouter portion is in a horizontal plane slightly above the plane of theupper surface of the bell crank 155 and intersecting the lug 154 of thecrank plate. The free' end 169, of the push bar 165 is guided tomoveapproXimately in a prede termined pathby means of two fixed lugs 173 and 174, spaced upon opposite sides of the push bar 165 and projectingupwardly from the baseplate 45. f

When the switch lever 48 is in an olf position at the limit of theanti-clockwise movement, as shown in Figs. 2, 3, and 5, and when thecrank plate 151 is in any position between its extreme inoperative oranticlockwise tion as shown in ter position, the push bar 165 will bemoved 1n response to; theclockwise rotation of the by the fixed lugs 173andy tooth 59 is not in engagenirtjvith its notch 60, but dui-ing theremainderofthe"movement the tooth 59 engages in! its notch 60,

and the notch is made broad eiiough to per-A mit of therotation vof theswitch lever anticlockwise through a suitable arc,lwhile the' tooth 59is in its notch 60 to rotate the crank plate 151 anti-clockwise throughan arc equal to the are through which the crank would be rotatedclockwise by the operation of the motor 20, through a predeterminedperiod slightly greater than necessary to rel produce the sound from thelargest record which the machine is designed to utilize. lVhen theswitch lever 48 has been thus ro.-l tated manually, or otherwise', intoits eX'- treme clockwise position as shown in Fig. 9,

and is then released, it is returned by 'they its normal action of thespiral spring to l, and the on position as shown in Fig. crank plate isleft in` its extreme Wise position or initial inoperative position, thusspacing the free end of the push bar 165 from the lug 154.

' ,In any case, after the crank plate 151 has been rotated clockwisefrom its predetermined eXtreme anti-clockwise position by the continuousoperation of the motor 20 Vfor i any given period within the, prescribedlimit, it is evident that the crank plate 151 will be reset into itsextreme anti-clockwise the switch lever 48 clockposition to a positionat the opposite end of its path of motion, the spindle 132 beingpermitted to rotate anticlockwise `independently of its Worm ygear 131through the yielding action of the spring clip 138 in coperation withthe liber washer 137, which is provided to permit of position by movlnfthis rotation or adjustment of the spindle 132 with respect to the wormgear 131, as hereinbefore described. v' While this invention has beenshown as 'applied in a talking machine in which the rotary recordsupport is driven at a constant angular rate of rotation by a constantspeed motor, 1t 1s evident that the invention might record, the switchlever 48 Y also. Vbe applied to a talking machine in which the recordsupport is driven at a constantly varying angular rate ofrotation,.either by a motor actuatedat a constantly varying speed or bya motor actuated at-a constant speed and connected'to the record supportbysuitable transmission means, to pro uce a constant surface speed ofthefrecord atzthe44 oint of engagement of the record by the sty us. v

Although only a single form has been shown in which thisinvention may beembodied, it is evident that the invention is not limited in itsapplicaton ltjtlie specific construction illustrated, but ight beembodied in various other forms without departing from the spirit of theinvention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to protectby LetteisPatent lofthe United States is:

1. The combination with a rotary member, of a motor 4'for actuating saidmember, an element arranged to move with respect to said member, meanscontrolled 4by the movement of said element to cause the stoppage ofsaidrotar'y member, and secondary means automatically actuated indeendently of said element, to stop said mem er.

2. The combination with a rotary member, of a motor for actuating saidmember, an element arranged to move With respect to said member, meanscontrolled by the movement of said element to cause the stoppage of saidrotary member, and secondary means automatically actuated independentlyof said element, to stop'said member after said motor has been incontinuous operation for a predetermined period.
